The youth of Genghis was passed in one ceaseless struggle to regain the whole of his birthright. His most formidable enemy was Chamuka, chief of the Juriats, and for a long time he had all the worst of the struggle, being taken prisoner on one occasion, and undergoing the indignity of the cangue. On making his escape he rallied his remaining followers round him for a final effort, and on the advice of his mother, Ogelen Eke, who was his principal adviser and stanchest supporter, he divided his forces into thirteen regiments of one thousand men each, and confined his attention to the defense of his own territory. Chamuka, led away by what he deemed the weakness of his adversary, attacked him on the Onon with as he considered the overwhelming force of thirty thousand men; but the result dispelled his hopes of conquest, for Genghis gained a decisive victory. Then was furnished a striking instance of the truth of the saying that "nothing succeeds like success." The despised Temujin, who was thought to be unworthy of the post of ruling the Mongols, was lauded to the skies, and the tribes declared with one voice, "Temujin alone is generous and worthy of ruling a great people." At this time also he began to show the qualities of a statesman and diplomatist. He formed in 1194 a temporary alliance with the Kin emperor, Madacou, and the richness of his reward seems to have excited his cupidity, while his experience of the Kin army went to prove that they were not so formidable as had been imagined. The discomfiture of Chamuka has been referred to, but he had not abandoned the hope of success, and when he succeeded in detaching the Kerait chief, Wang Khan, from the Mongols, to whom he was bound by ties of gratitude, he fancied that he again held victory in his grasp. But the intrigue did not realize his expectations. Wang Khan deserted Genghis while engaged in a joint campaign against the Naimans, but he was the principal sufferer by his treachery, for the enemy pursued his force, and inflicted a heavy defeat upon it. In fact, he was only rescued from destruction by the timely aid of the man he had betrayed.
